' 4 Claims.

This invention relates generally to an amusement deviceI andparticularly kto an airplanel amusement device.

The main object of this invention is the construction of anextraordinarily simple and efficient form of amusement. device, whichwill give the user thrills similar to those experienced in an airplane;

'I'he second object is to produce an amusement device in which a car canbe swung in a circular orbit in a vertical plane, and in which arotating movement can be imparted to the car on its longitudinal axiswhile traveling about in its circular orbit.

'I'he third object is to construct a device of the type referred towhich is selectively usable in a manner to permit the car to be ilxedwith relation to its supporting arm, or to revolve on the longitudinalaxis of the car as may be desired. I accomplish these and other objectsin the manner set forth in the following specification as illustrated inthe accompanying drawings, in which:

Fig. 1 is a front elevation of the device show ing same in a rotatingposition.

Fig, 2 is a view similar to Fig. 1 showing the position of the car atits tlrst quarter of a revolution of travel.

Fig. 3 is. a view similar to Fig. 2, but showing the car at` the halfwayposition, that is, at its uppermost position of travel.

Fig, 4 is a view similar to Fig. 3, but showing the car at the thirdquarter of travel.

Fig. 5 is a side elevation of the device showing the parts in theposition corresponding with those shown in Fig. 1.

Fig. 6 is a section taken along the lines 3-8 in Fig. 5.

Fig. I is a section taken along the lines 1-1 40 in Fig. 6.

Similar numbers of references refer to similar parts throughout theseveral views.

Referring in detail to the drawings, there is shown a base' I0, whichmay be secured to a foundation in any convenient manner. From the baseI0 rises the slightly inclined mast il through whose head I2 extends thehorizontal, stationary. shaft I3 upon which the arm bifurcated i4 isrevolvable. vAttached to the hub I5 of the arm i4 50 is a gear I 3 winchmeshesV with the pinion I1 of the driving motor I3, which iscontrollable from the box I 3 on the upright 23.

Secured to the stationary shaft I3 is a beveled gear 2i, which is alsostationary since it is secured to the shaft I3 by means of a pin 22, and

(ci. 21a-4 6) the shaft I3 is secured to the head I2 by means of a key23.

The gear 2| meshes with the gear 24, which is Becured'on'the shaft 25,which Journals in the bearing 23. The shaft 2 3 has formed on the en dthereof a clutch jaw 21. In alignment with the bearing 23 is a bearing28 on whose side facing the clutch jaw 21 is formed a slot 23.Journalling in the bearing 28 is a shaft 30 whose end 3| also vJournalsin the clutch jaw 21. 4On the shaft 30 is slidably -keyed a clutch Jaw32, which can be moved into engagement with either of the members 21 or28 by the forked arm 33, which is pivotally mounted on the pin 3l, andmay be held in any desired position by means of the bolt 35, whichpasses through the slot 36. A hand lever 31 is formed integral with theforked armv 33, and facilitates the movement of-the clutch Jaw 32.

On the shaft 30 is also secured a bevel gear 33,l which meshes with abevel gear 39 on the trun- 4nion 40 of the car 4I, whose opposite end issupported by a trunnion 42. 'Ihe trunnions 40 and l2 Journal in theoutermost ends 43 of the arm i4. The arrangement of thev seats 44 in thecar li may of course be varied greatly without departing from the spiritof this invention.

Attention is drawn to my copending application, Ser. No. 719,874, issuedJan. 8, 1935. as Patent 1,987,004 over which this device is animprovement.

The operation of the device is as follows: Assuming that it is desiredto operate the device in the manner described in myfabove identiiledapplication, the operator moves7 the lever 31 so that the clutch jaw 32will engage the slot 23, the bearing 28 thereby locking the gears 33 and39, and preventing the rotation of the car 4i with relation to the armI4. If, however, the car 4I is to be rotated on its trunnions 4 0 andl2, the lever 31 is moved to the position shown in Fig. 6. In thisevent, the shaft 25 is enabled to rotate the car li at a speed whichwill hold the car 4i upright in its lowermost and uppermost positions asshown in Figs. 1 and 3, and to turn it to intermediate positions asshown in Figs. 2 and 4.

It will be observed that the arm Il is in the form of a triangle, ofwhich the car 4| forms 50 the base, which naturally provides thegreatest amount of rigidity for a given weight.

While the clutching mechanism has been shown adjacent to the car 4I, itis obvious that it can be placed nearthe upper end of the drive 55without departing from the spirit of this invention.

I claim:

1. 11n an amusement device of class scribed the combination of anupright mast. a stationary, horizontal shaft disposed at the upper endoi' said mast, a bifurcated arm having its closed end revolvablyattached to said stationary shaft, a prime mover Yfor revolving said armin a vertical plane, a car revolvably mounted on a longitudinal axisbetween the bifurcated ends oi said arm. said axis lying within saidvertical plane, a gear secured on said stationary shaft and a gear drivemeshing with said stationary gear extending to said car whereby said carwill bevrevolved at the same rate on its longitudinal axis that it isrevolved in said vertical plane.

2. The device described in claim 1 in combination with clutch meansadapted to render inoperative the gearing for rotating said car on itslongitudinal axis and to lock said car against rotation with relation tosaid arm.

3. A device of the class described having an A-shaped frame revolvablymounted in a vertical plane with the vertex of said frame at the axis ofrotation. both arms of said frame lying within said plane, a carrotatably mounted between the outermost ends ot said A-shaped framealong the longitudinal axis of the car, said car axis lying within theplane of rotation of said i'rame and normal to the radius of rotation ofsaid frame together with gearing for rotating said car in a manner thatit will be right side uppermost in vertically opposite positions and inreverse positions in horizontally opposite positions.

4. An amusement device having in combination an upright supportingstandard. a horizontal shaft disposed at the upper end oi' saidstandard, an arm revolvably mounted on said shaft, a prime mover: forrevolving said arm, a car mounted on an axis lying within the plane inwhich said arm swings and normal to the radius of said arm permittingsaid car to rotate on its longitudinal axis and means for selectivelylocking said car against rotation on its longitudinal axis, or causingsame to be rotated thereon in a manner that said car will be upright inits uppermost and lowermost positions.
